[PATCH 09/93] libceph: unregister request in __map_request failed and nofail == false

[Kamal Mostafa]

3.8.13.10 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: majianpeng <majianpeng@xxxxxxxxx>

commit 73d9f7eef3d98c3920e144797cc1894c6b005a1e upstream.

For nofail == false request, if __map_request failed, the caller does
cleanup work, like releasing the relative pages.  It doesn't make any sense
to retry this request.
